Renée Zellweger cut a super svelte figure as she arrived at Giorgio Armarni’s One Night Only New York event on Wednesday.

The 44-year-old actress put together a sleek black power suit with a cute bow-tie on the front, and let her outfit do the talking as she pulled her hair into a low pony

All-black was seemingly the theme of the night- Hilary Swank glittered in a sparkly shirt and black cigarette pants, Dianna Agron showed off her unusual style in a button dress, and Naomi Watts looked glamorous in a maxi skirt and silky grey top.

Also on trend were Olivia Palermo and Olivia Munn in dazzling dark ensembles.

However it wasn’t just the ladies making an entrance, Leonardo DiCaprio was his usual suave self in a smart suit and striped tie.

Unless there is some legitimate medical reason (doubtful), surely a good surgeon would have tried to talk her out of it, or at least pointed out that she'll no longer look like herself? If not for the headline, I would never have recognised her.
